'SPECIFICATION forming part of Letters Patent No. 693,208, datedFebruary 11, 1902. Application filed November 25, 190.1. Serial No.83,648- (No model.)

To all whom t Netty concern:

Be it known that I, FRANK H. ARMSTRONG, a citizen of the United States,residingv at Auburn, in the county of Cayuga and State ltransversely-disposed slots, one for every lo- Fig. 7 is a detail planof the carriage.

cation-pin, instead of the two longitudinallydisposed curved slots ofthe patent, to form this location arm or plate separate from the typewheel or segment to which it is geared, to improve the key-'levermechanism and the connections between the same and the typewheelcarrier, and to provide a novel and efficient mechanism for raising andlowering the type-wheel to bring its several series of characters intothe proper planeA for printing the upper or lowercase letters or thecharacters or signs therebetween. These objects, together with othershereinafter set forth, l accomplish by the mechanisrn'shown in theaccompanying drawings, in which- Figure lis a plan of the machine withmy improvements applied. Fig. 2 is a side elevation thereof. Fig. 3is atransverse vertical section on the line 3 3 of Fig. l. Fig. 4 is adetail perspective of the mechanism for raising the type-wheelinto itsdifferent printing planes. Fig. 5 is a plan of the location plate orarm. Fig. 6 is an inverted plan of the carriage and the overlyingframe-plate. Figs. 8 and l9 are detail views of carriage,guidingrollers, and slides. Fig. lO is a detail perspective of theline-gage-and the type-wheelcentering lug and a portion of the platen.Fig. l1 is a plan of the notched centering or locking disk.h Fig. ll2 isan enlarged side elevation, partly in section, of thetype-wheelelevating mechanism. Fig. 13 is a detail view.

A designates the bed or frame of the machine, preerably of openrectangular form and provided between its ends with a horizontalfulcruln-bar A', having a slot a for every key-leverB. The rear ends ofthe keylevers extend i'nto slots formed in the vertical location-pins C,which pins are all on a common line extending from side to side of vthemachine and at their upper and lower ends pass through apertures in twotransverse bars forming portions of the frame at the rear thereof. Thusas the front ends of the key-levers B are depressed their rear ends willraise ythe respective location-pins C. The key-levers lBv are returnedto their normal positions by spring rods or wires I), extending from atransverse angle bar A2,

nearthe frontof the machine, rearwardly to links b2, depending from thekey-levers in rear of their fulcrum-points. ln order that these springrods or wires may be readily inserted and removed, their front ends arebent downwardly and after having been passed through transverseapertures a2 in the vertical flange of the angle-bar 'A2 are theninserted inthe'vertical apertures formed in the horizontal member ofsaid angle bar, the strain on the free rearends of the spring-rodsserving to retain their front ends in proper position. bar crossing thekey-levers B above their fulcru'm-points and serving to preventaccidental displacement thereof. v

' Every key-lever B is provided in rear of its fulcrum with a downwardlyand rearwardly projecting arm b3, provided with an inclined `slot b4,whichk receives a lateral pin d, projecting from every one of a seriesof vertically-swinginglevers D, pivoted at their lower ends on atransverse rod d', extending from side to side of the frame. Theselevers D are in practice provided with arms cl2, on which said pins aremounted or formed. Itfollows,l therefore, that whenever a key isstruck'thq rear end of the lever will rise and carry afpifrr C up withit, and a lever D will be swung rearwardly, and on release of the keythe. springs b will return the parts quickly to their vnormal positions.f-

ing key-lever. The longitudinal rod E is l mounted to reciprocatebetween four grooved I antifriction-rollers @,carried by the fourslidese', mounted in oblique guideways e3, formed or secured upon the underside of a horizontal plate A3, forming a rigid part ofthe frame A, towhich it is connected by being screwed to four posts a", rising from thesides of the main frame. These slides are adjusted in the guideways bythe adjusting-screws e3 and are held in their adjusted positions bymeans of the set-screws e4, which pass down through slots in the plateA3. (See Figs. 8 and 9.) Thus the carriage may be held to reciprocate ona straight line and wear be taken up from The type-wheel carriage E isretracted bya spring e5, extending from adepending lug e6 on thecarriage to a tensionscrew e7, mounted in a depending ear or lug a5 atthe front end of the frame-plate A3. The ends of the cross-bar E2 areprovided with rollers @10, which bear firmly against the under side ofthe frame-plate A3 and prevent the carriage from tilting or rocking. Therear end of the carriage E is provided with a vertical post E3, on whichthe type-wheel F has both rotary and vertically sliding movement. Thistype-wheel F is provided with three annular series of letters orcharacters, the upper series being the letters of the lower case, thenext series the gures and signs, and the lowermost series being theupper case or capitals. The type-wheel F is provided beyond its axiswith a vertical opening, into which extends a vertical arm g on therotary hub or sleeve G, mounted to rotate on the carriage-post E3. Thishub below its arm g is provided with the peripherally-notchedcentering-disk H and below this with an operating-gear g and finallywith a spacing-washer or wear-plate g3. The upper end of the typewheelis provided with a concentric liftinghub f, having an annular groove f',to be hereinafter referred to.

J designates the horizontally-swinging location-plate overlying the frame-plate A3 and pivoted at its front end to the stud e3, rising from thefront end of the carriage E, so as to be moved back and forth with thecarriage. The rear edge of this location arm or plate is held down bythe two armsj3 and is provided with gear-teet-hj, which mesh with theoperating-gear g. The location-plate J receives its horizontallyoscillating orswinging movement by means of a series of angular slotsj', disposed in the direction of the length of the plate and overlyingthe location-pins C, there being a slotj' for every pin. The slots atopposite sides of the center of the carriage and location-plate inclinein opposite directions, so that the pins and slots at one side willcause the location-plate J to swing to the left when moved rearwardly bythe carriage E, and those at the other side will cause thelocation-plate to swing in the opposite direction. It will be seen, ofcourse, that when a key-lever is depressed it raises its pin O andceases projects it through the proper slot j', whereupon as the carriageE is moved rearwardly by the further movement of the key-lever thelocation-plate J will move with it, and iu so moving to the rear theinclined wall of the slotj will cause the plate J to swing and rotatethe type-wheel F through its gear g and arm g. The angularity of theslotsj decreases gradually toward the outmost slots, where it isscarcely perceptible, though suficient to impart the slight movementnecessary. The rear ends only of the slots ,7" are inclined, as the endsnext to the operator must be parallel, since the location-plate after ithas rotated the type-Wheel must move forward on a right line with thecarriage and said wheel. When the type-wheel is moved to its printingposition, its centering-disk H will engage the centering-lug H on theframe in the usual manner, and so when the parts are returned to theirnormal positions the location-plate J will be centered by the lug K5 andthe notchj. The location plate or arm J is supported in rear of its axise8 upon two antifriction-Wheels e", carried by the carriage E andprojecting up through the frame-plate A3, these wheels e being on thearc of a circle struck from the axis e3.

I will now describe the mechanism for raising the type-wheel to bringits different series of letters or characters into the proper plane forprinting.

K is a vertically-movable angular slide mounted in suitable bearings inthe frame and extending up through a loop Zon the upper end of a bracketL, secured on the upper side of the frame-plate A3 and there providedwith a rearwardly-projecting arm K', provided on its upper side with atransverse rib 7a and screw-holes at opposite sides thereof. On the armK is secured by screws 7c the forked arm or horizontal member K2 of theangular slide K, the forked end 7e3 of said arm K2 entering the groove fin the hub fof the type-wheel F and suspending it thereon, so that asthe slide K is raised and lowered the type-Wheel will he movedvertically therewith, the slot in the fork allowing the typewheel to bemoved into and out of its printing position by the key-levers, asheretofore described. By adjusting the screws t" the type-Wheel F may beadjusted so that its type will print full face and not print heavier atthe top than at the bottom of the letters, the rib 7c serving as afulcrum on which the forked arm K2 rests. The upper end of the bracket Lis provided with a screw Z', which bears against the slide K to take uplost motion, and below the loopZ the bracket L is provided with a notchZ3, to be presently described. The vertical slide is provided on itsfront side in rear of the bracket with a short lug or projection 7a4.The lower end of the slide K passes through a second bracket L3, havinga take-up screw Z3.

M designates the ligure or sign key-lever at the left of the machine,and M is its trans- IOO IIO

verse rock-shaft', mounted in suitable bearings in the frame A andVprovided at its inner end with a rearwardly-extending arm or crank m,which engages the lower slotted end of the slide K, as shown in Fig. 4,to raise the slide against the'actiou of its spring Z4, and with it thetype-wheel F.

N designates the cap-lever, having its hub n turning freely on therock-shaft M and provided with a laterally-projecting finger n',overlying the key-lever M. Depending from the lever N is an angle-armN', to the inner en'dof the horizontal member N2 of which is connected,by a link n3, the lower cranked end o of a vertical rock-shaft O,extending up thro-ugh the frame-plate A and provided with alaterally-projecting latch-arm o. These parts are returned to normalposition by a spring n4. The latch-arm o projects through the notch-Z2in the bracket L into the vertical path of the lug or projection 7a4 onslide K. It

and Withdraw latch-arm o' out of the path of lug 104, and then' thefinger n' will bear ydown on and operate key-lever M, which will raisethe slide K far enough to bring the lowermost series of type into theprinting-plane, where they may be held, if desired, by holding thekey-lever M depressed and releasing key-lever N till the latch-arm oswings under the lug or projection h4, where it may remain so long ascapitals are to be printed.

R designates any form of ribbon mechanism, and P designates aroller-platen mounted on a paper-carriage Q, of which Q isthe'escapement-lever. mechanisms are not further described herein, sincethey are not specifically claimed.

The term type-wheel is used as a convenient means of including asuitable form of printing segment or wheel however the printing`characters are formed, and so the term location-plate is used as a broadterm regardless of Whether this element isa simple plate or aframework'or composite structure.

In order that operator may bring the lines on ruled sheets into registerwith the printing-plane, I have provided what may be called a line-gageH2, formed like a yoke, with its two arms h h extending up from a base72,', provided with slots h2 h2, through which the screws h3 h3 passinto the frame-plate A3. The upper edges of these' arms are straight andare on a line forming the base of the printing-plane. In practicethebase h is cast or otherwiseprovided with a central boss h4, having asplit into which is driven the beforementioned type-wheel centering orlocking lug H", formed of a hardened -steel blade.

By adjusting the base h the lug H may be These inking and carriagebrought in'to the exact position required. The arms'h 7i curverearwardly at their upper ends toward the platen P, and by placing apencil-point on the upper edge of an arm h and against the sheet ofpaper lines may be ruled by sliding the paper-carriage back and forth orby rotating the platen according to Whether horizontal or vertical linesare desired.
